Dimensional lumber tape measure

I hope it’s not against the rules here, just saw this woodworking related xkcd that I enjoyed and thought it might be appreciated here:)
Have you hard of our lord and savior, the metric system?
Even metric is under-sized on dressed timber 4x2" ~ 100x50mm => 90x45m dressed
Yeah, but then we just use the 90x45mm as a measurement...
Also if I remember correctly it's sold as 89x44. 45mm was only used for I-joists
